Badger culling “doesn’t have a big impact” on bird numbers

According to the British Trust for Ornithology (BTO), badger culling as part of an effort to combat M. tuberculosis has no real effect on bird populations. the study (PDF).

Badgers have a variety of diets, including eggs and birds, and previous studies have shown that they precede bird’s nests that nest on the ground, especially when the preferred prey of earthworms is low.

BTO volunteers have increased the population growth rate of 58 breeding birds in the former Anaguma selection area in Gloucestershire and Somerset for a five-year selection period following a five-year baseline period (2008-2012). We surveyed over (2013-2017). The same region of the country before the selection.

They found that the above-ground nesting species, the skylark and the worm, were slightly positive in the badger control area, while the lapwing population growth was slightly negative in the control area. It was.

However, there was no significant association between populations of other ground-nesting species and badger-controlled areas.

Some higher nesting species, such as trees such as starlings, greenfinch, and long-tailed tit, have increased within the badger’s controlled area, while other species such as wood pigeon, linnet, and long-tailed tit have increased. We have shown a decline in populations in these areas.

Research conclusions

The authors of a study funded by Natural England concluded that badger removal had little effect on bird population growth and that there were no significant community-level changes in the study area. They said the results could inform the assessment of the broader ecological impact of badger culling.

Defra introduced farm-led badger culling in 2013 as part of a 25-year cattle tuberculosis eradication program for the United Kingdom.

Badgers are believed to be the major wildlife transmitters of Mycobacterium tuberculosis in the United Kingdom. Its population is estimated to be 384,000 in the United Kingdom, much larger than in the 1980s.
